我试图使用javascript获取位置并传递坐标以在邮票上应用戳记,但它无法正常工作.下面是我用来捕获鼠标指针坐标的函数.

function divMove(e){
    var div = document.getElementById('stamp');
    div.style.position = 'absolute';
    //div.style.top = e.clientY + 'px';
    //div.style.left = e.clientX + 'px';
    var box = div.getBoundingClientRect();
    mouse_top = e.clientY;
    mouse_left = e.clientX;
    var diff_x = mouse_left - box.left;
    var diff_y = mouse_top - box.top;
    div.style.top = ((Number(div.style.top.replace("px", "")) - 1) + diff_y) +"px";
    div.style.left = ((Number(div.style.left.replace("px", "")) - 1) + diff_x) +"px";
    document.getElementById("data").innerHTML =
        "mouse_top:" + mouse_top + "<br>mouse_left:" + mouse_left
}

以下是使用iText处理冲压件的后端代码:
